Istanbul (Online): New era of Recep Tayyip Erdogan may start from Today Only One (Yes) or (No) will decide the future of Turkish President. Voting is under way in Turkey,a landmark referendum that will determine whether President Recep Tayyip Erdogan will be granted sweeping new powers.

Recep Tayyip Erdogan is seeking to replace Turkey's parliamentary system with an executive presidency.Supporters say the move would streamline and modernise the country, but opponents fear it could lead to greater authoritarianism.

A "yes" vote could also see Mr Erdogan remain in office until 2029.

On Saturday, Turkish politicians made their final appeals to voters preparing to cast their ballots on one of the most sweeping programmes of constitutional change since Turkey became a republic almost a century ago.

Some 55 million people are eligible to vote across 167,000 polling stations, with the results expected to be announced late on Sunday evening.

If the referendum vote falls in Mr Erdogan's favour, it would give him vastly enhanced powers to appoint cabinet ministers, issue decrees, choose senior judges and dissolve parliament.
